Product Overview

Inspired by the Canadian Military who regularly dive in Arctic waters, the MK3 sock has the same tri-layered system as our popular MK3 Undergarment:

1. Outer Nylon (with heel stretch panels)
2. Primaloft
3. Inner Fleece

Features

• Our Most extreme cold water sock available
• Breathable, moisture-wicking, high loft, insulating polypropylene Polar Fleece inner lining
